Abstract:  Integration over lines is the mathematical basis of many modern methods of tomography, including Computerized Tomography scans. In this talk, a recent geometrization using indefinite metrics of signature (2,2) is presented of the seminal work of Fritz John on the problem. The contemporary mathematical background is 4-manifold topology and the use of neutral metrics to explore co-dimension two problems.
